Instructions for RTD2672
Power Supply Connection:
- Connect the input voltage (VIN) between 2.7V and 5.5V to the input pin.
- Ensure proper decoupling capacitors are placed close to the VIN and GND pins.
Output Configuration:
- Set the desired output voltage using the feedback resistors for adjustable configurations.
- For fixed output voltages, use the appropriate configuration as specified in the datasheet.
Thermal Considerations:
- Ensure adequate heat dissipation if operating at high load currents.
- Place the device on a PCB with sufficient copper area or heatsink if necessary.
Switching Frequency Adjustment:
- The switching frequency can be adjusted by an external resistor connected to the FREQ pin.
Protection Features:
- The device includes overcurrent protection, thermal shutdown, and undervoltage lockout (UVLO).
PCB Layout Recommendations:
- Keep the input and output capacitors as close as possible to the device.
- Use wide traces for power paths to minimize voltage drops and heating.
Testing and Troubleshooting:
- Verify all connections before applying power.
- Monitor output voltage stability under varying load conditions.
- Check for correct operation of protection features during testing.
